小米：玄戒O1不是向Arm定制的

Group 1 - The Xiaomi Xuanjie O1 is not a custom chip from Arm, but rather a 3nm flagship SoC developed independently by Xiaomi's Xuanjie team over four years, utilizing Arm's latest CPU and GPU standard IP licensing without adopting Arm's complete solution [1] - The CPU of the Xuanjie O1 features a super-large core with a maximum frequency of 3.9GHz, significantly exceeding industry standards, achieved through numerous innovations and hundreds of layout iterations [1] - The Xuanjie O1 has redesigned over 480 standard cell libraries, nearly one-third of the 3nm standard cell library, and employs innovative edge power supply technology and self-developed high-speed registers [1] Group 2 - The Xiaomi 15S Pro, equipped with an external baseband, provides a user experience comparable to other flagship smartphones and supports 5G [3] - In internal tests, the Xiaomi 15S Pro achieved a DOU (Daily Usage) of 1.47 days, closely approaching the 1.50 days of the 15 Pro, with minimal differences in daily usage [3] - Xiaomi has integrated a fully independent 4G baseband in the recently released Xuanjie T1 chip, which is already used in the Xiaomi Watch S4 [3] Group 3 - The Xiaomi 15S Pro supports always-on display (AOD) features, including customizable clock and signature settings, while managing power consumption by defaulting to a 10-second display [4] - The device includes a "motion sickness relief" mode that uses visual compensation to alleviate symptoms during vehicle movement, activated through built-in high-precision sensors [5] Group 4 - The camera app of the Xiaomi 15S Pro has undergone a simplification process, automatically triggering night mode in low-light conditions without requiring manual activation [7] - In professional mode, red stripes appear in bright areas of the preview to indicate potential overexposure, a common feature in professional photography equipment [8]
